Abstract (en)

[origin: WO2014206489A1] Various example embodiments are disclosed herein. A technique is provided for controlling a response by a mobile station (MS) to a radio link failure detected by the MS in a dual connectivity wireless network in which the MS is connected to both a master base station (master BS) associated with a primary cell and a secondary base station (secondary BS) associated with a secondary cell. The MS may detect a radio link failure for a radio link between the MS and the secondary BS. In response to detecting the radio link failure, the MS may perform one of several preconfigured responses, or the MS may notify the master BS of the radio link failure, receive an instruction from the master BS, and then perform operations or respond to the radio link failure according to the received instruction.
